For Matt's point of view, the dinner had been interesting, to say the least. Maybe bizarre.
To sit there and listen while two sisters discuss the sex you've just had with them was not an everyday event for him.
But Lucy had heard the effects of Kylie's orgasms in Kylie's moans and, seeming to Matt to be on the spectrum, knowing no inhibitions about such things, wanted a full download from Kylie on it.
Kylie in return wanted to find out as much as she could about her sister's first orgasm; indeed, her sister's first physical contact at all with a man.
It was difficult for Matt to read what Lucy thought about all of this. He still doubted whether someone like Lucy, who had a strong aversion to physical contact with anyone, could actually enjoy sex. And yet he could see Lucy was intrigued by the possibilities. Kylie's very vocal broadcasting of her enjoyment of her own orgasms had registered with Lucy and challenged her assumption that sex was a bit ordinary. Kylie's story of squirting, a bit gross though Lucy thought it was, raised her curiosity further.
Kylie was simply pleased to have been able to bring Matt within her orbit and get him into bed. She'd had the hots for Matt ever since she'd first seen him when she visited Lucy during Lifesavers duty and found Matt sitting next to her with his shirt off. His tall, slender and totally ripped body had been an object of desire ever since; compounded, she reassured herself, by his great personality.
For her, Matt offered the solution she needed of a partner that seemed to satisfy her need for a relationship based on a strong attraction while not annoying her sister if it became a live in one. But that sort of relied on Lucy having sufficient sexual interest in Matt to, in effect, want to share him in a polygamous relationship.
Lucy's reactions were far more complex. She had always fancied Matt. But for her, the attraction seemed to be more located in the head than, shall we say, the groin. She fancied having a romantic relationship with him, but still lacked the sexual drive to think it could be sexually based. If sharing Matt with her sister let her meet her former objective, that was no problem to Lucy. If she could learn how to enjoy and want sex, in her mind that would be better still.
As Matt left after dinner, he remembered Kylies warning that Lucy had been instructed to give him a prolonged hug. She did, and he reciprocated, pulling her in maybe just a bit more than Lucy offered. But Matt could tell Lucy was still blocking her mind to the experience. She did it because she had to, not as an exchange of human feelings. Still, it was a start. Maybe Lucy would learn to relax and enjoy it over time; or maybe she wouldn't.
Matt had been invited back the following Wednesday, signalling to him that, with the Saturday lifeguard duty follow-on, this was something of a standing, twice a week engagement. For the time being anyway.
The first Wednesday had been a bit awkward when Lucy stripped down out of her work gear into a pair of briefs made of heavy cotton and a highly structured bra that was impermeable to nipple stimulation. To say that the results of Matt trying to stimulate her through those garments were a bit ordinary was an understatement; because it was far too early for Lucy to have permitted Matt to slip his fingers inside the garments, let alone expose her.
However, the problem having been identified, thereafter, with some push from Kylie and the provision of one of her own bikinis, Lucy presented herself in a small bikini top and bottom, almost completely unlined and made of a thin stretch Lycra, which gave much better results. It was certainly much briefer than Lucy was comfortable with and - at that stage - wasn't something she'd be seen in public with. But in her own mind, she acknowledged she was working towards fully exposing herself to Matt and accepted it as a stepping stone towards that.
As for Kylie? Having discovered Matt could consistently deliver her g spot orgasms, she took all she could get.
In the past Kylie had also often felt a bit let down by sex, even after climaxing. She always felt she wanted a little bit more. With Matt having demonstrated that she could also be multi orgasmic, Kylie could ensure she well and truly drained any frustration Matt felt about pleasuring Lucy without Lucy offering any reciprocal benefit.
When Matt accompanied Lucy home from Lifesaving duty three weeks later, he could reflect on the fact some progress had been made.
Matt recognised Kylie's influence when, having discovered on that first day that he wore speedos under his board shorts, Lucy announced they could the only garment he retained on as he lay next to her, fingering her.
The previous Wednesday, Lucy had let him expose her nipple, and stimulate it directly, by peeling back the bikini top triangle without taking it off, but the fingering of her clit was still through the thin material of her bikini pants. Mind you, Lucy had permitted some more than superficial digital penetration of herself as Matt's finger explored Lucy's vagina by pushing the material of her pants into her with his finger.
And for the first time, Lucy had wrapped her hand around Matt's speedo sheathed erection as he fingered her. She'd made no attempt to use her grip to stimulate him to a greater extent than that provided by the wrapped hand; but it was a start.
Matt had grown familiar with Lucy announcing at the start of each session what the new rules were for the day. And he could often see Kylie's influence in setting them. On this afternoon, as Matt waited in her bedroom, stripping down to his speedos, Lucy disappeared into her ensuite bathroom and re-emerged in the now familiar small black bikini.
She sat on the edge of the bed, looking nervously up at Matt standing in front of her; her eyes dropping occasionally to the swelling bulge in Matt's speedos right in front of her. She seemed, once again, to steel herself for what lay ahead as she spoke...
"Today I'm going to go topless, plus you can stick your hand down my pants. And I'll put mine down yours."
Matt watched as Lucy swung her legs onto the bed and nervously shuffled across to the centre of it. She closed her eyes as she reached behind her back to pull the bow on the lower tie of her bikini top and lift it over her head; folding the tiny piece of material neatly before placing it on her bedside table.
The slow, teasing revelation had been exciting for Matt to watch. He felt an additional swelling in his pants as her breasts had fallen out of the top as she lifted it over her head. A near perfect match for Kylie's, they were as beautiful and sexual a pair of breasts as Matt had ever seen and seeing them fully exposed like that was a whole lot more exciting than a minimalist exposure of the nipple by pulling the material to the side.
But the swelling in his pants reminded Matt to undo the drawstring on his speedos. He normally kept it tightly tied to retain the erection that was an inevitable feature of these interactions with Lucy; not wanting to traumatise her with a premature exposure.
As Lucy laid back on the bed in her usual, arms by her side, 'do what you have to' pose, Matt climbed on the bed and laid down alongside her. The pronounced gap between their bodies, which had been a feature of their earlier interactions, had all but disappeared. There was now significant contact between them for much of the length of their torsos; Matt erection falling conveniently at the hand Lucy had alongside her.
Almost robotically, Lucy slipped her hand down Matt's pants and wrapped her fingers around the erection within.
This closing of the gap hadn't been a stated rule, so much as an adaption to circumstances. It especially facilitated Matt leaning across and sucking and tonguing Lucy's far nipple, while playing with the closer one with his lower hand. Because she did seem to respond readily to gentle nipple stimulation.
But there were still limits. In any normal interaction, Matt's upper leg might well have rested over his partners as he lay on his side alongside, fingering her. For Lucy, Matt still regarded that as a step too far.
The foreplay routine hadn't yet changed much. Cuddles and kissing were definitely not Lucy's thing. But the gentle stroking of her lower torso with his fingers - extending from her navel down into her crotch - continued to be effective.
The thin bikini pants had considerably increased Matt's own enjoyment of this because he could actually feel Lucy's vulva respond to his stroking; opening out like a flower as her swollen bud and receptive vagina were easily felt; more so as her body moistened the material.
This time he included rimming the waist of her bikini bottom; sliding his finger under it to glide his finger across the bare flesh of her raised mound. He confirmed his expectation that Lucy wouldn't be clean shaven down there. She was fastidious about a tidy bikini line but it never seemed to Matt that Lucy would go for a full Brazilian. Instead he found a sparse matt of fine short hair.
Once her nipple hardened, he started playing with those too; revelling in sucking the far one and feeling the closer one rise between the fingers of his lower hand.
All the while, he monitored Lucy's impenetrable countenance. She continued to lie down, frozen in place, her eyes closed; only her lips displaying any reaction to his pleasuring of her.
Matt could imagine the battle going on inside her. The sensory horror of him being in such close and intimate contact with her against the sexual pleasure; mild though the latter might so far be. And overriding all of that, her quiet, steely, determination to make herself more relationship ready.
Increasingly his fingers, then his whole hand, penetrated into her pants; at first still stroking her mons and then probing deeper to where he found her clit swollen and firm and her vulva well moistened.
